摘要
利用拟动力试验对T型钢半刚性连接钢框架在2种地震峰值加速度下的抗震性能进行研究,并对比分析了钢框架在柱顶施加竖向载荷和无竖向载荷等2种工况下的应变、位移和载荷变化,以及载荷-位移滞回曲线.结果表明:T型钢半刚性连接钢框架具有较好的变形能力,滞回性能良好,抗震能力较强,且随着地震作用的增大,钢框架的动力反应增大;竖向载荷对钢框架的层间位移反应影响较大,而对节点区域的应变和层间载荷的影响较小.
A pseudo-dynamic test is carried out to study the seismic performance of the T steel semi-rigid connection steel frame under two kinds of earthquake peak acceleration,and the peak strain,the displacement and the load variation of the T steel connection steel frame with and without the vertical load are analyzed and compared,together with the load-displacement hysteresis curves. Experimental results show that the T steel semi-rigid connection steel frame enjoys better deformation capacity and ductility performance,and the hysteretic performance is good, that explains the good seismic performance.The dynamic response is increased with the increase of the earthquake load; the vertical load has a great effect on the displacement response, but has little effect on the strain and the interlayer load for the semi-rigid connection steel frame.
